RE GULATING GAS-BURNER.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed February 5, 1907. Serial No. 355,796.

To all whom it may concern:

Be it known that I, WILHELM SoHMrrz, a subject of the German Emperor,and resident of No. 33-34 Valenvtinskamp, Hamburg, Germany, haveinvented certain new and useful Improvements in Regulating Gas-Burners,of which the following is a specification.

The present invention deals with a device for the regulation ofgas-burners.

The opening through which the gas enters is regulated by aneed1e-valve,- and the invention consisting therein is that the latteris triangular in shape, crosssection-wise.

The accompanying drawing represents a form of construction of theinvention.

Figure 1, a side view of the device. Fig. 2, a longitudinal section.Fig. 3, a view of the need1e-valve, on an enlarged scale. Fig. 4, thevalve in connection with a gas-burner.

The device consists of two parts a and b which are screwed one into theother. The ingoing part a has a bottom 0 in which four or more holes arebored, and in the middle and the lower side of the same a conicalpointed and triangular shaped pin e is fastened. The

part b is also provided with a bottom f, in the middle of which is abore-hole opening 9 which will be narrowed and widened by the triangularpin 2 according to the said pin being moved up and down by turning ofthe part a. As soon as the device is adjusted, the parts a and b can befixed by the binding screw i, which prevents the inner part a fromunscrewing itself from part b, and the arm h attached to part 6 holdsthe part a from releasing itself from the lower one.

According to this invention the regulating opening g can never be closedcompletely.

I claim:

In a regulating gas burner, the combination of a base part having aninternal threaded chamber and carrying at one end a triangular needlevalve around the base of which are gas passages opening from saidchamber, a second part screwing upon said base part and having anopening into which the needle valve projects, a set screw for holdingsaid part in adjusted position, and a separate device for preventing theseparation of the two parts above mentioned, substantially as described.
